Abstract

A water intrusion warning film for radiating holes on laptop bottom cases comprises a base, a mini-cell, a control chip, a buzzer, a side-A conductive coating layer, a side-B conductive coating layer, glue and a glue protective film. The water intrusion warning film for the radiating holes on the laptop bottom cases is characterized in that the side-A conductive coating layer and the side-B conductive coating layer are respectively connected to a control chip through leads, and the control chip is connected with the mini-cell and the buzzer. The film is convenient to stick, cannot affect heat dissipation of laptops and other functions such as capability of being connected with peripheries and the like, can warn users once contacting with conducting liquid, and can be removed easily once the users want to change or abandon the film. In addition, the film is easy to process, low in cost and easy to popularize.

Description

Notebook computer drain pan louvre water inlet warning pad pasting

Technical field

The present invention relates to a kind of warning device, relate in particular to a kind of notebook computer drain pan louvre water inlet warning pad pasting.

Background technology

The universal life that is very easy to people of computer; Yet the electronic component of computer can not get wet; Will pay special attention in use, but some user can be placed on water tumbler when using notebook computer by the computer, as if knocking the glass over because of carelessness; Conducting liquid such as water is flow to not to be had to find that in time liquid just is easy to get into computer internal damage computer below the notebook drain pan.

At present, though there is drain pan to seal the notebook computer of no louvre fully, on the notebook computer drain pan of market majority louvre is arranged all, because the suction of radiator fan when water is near the drain pan louvre, is easy to be sucked into computer inside.

Though the protective sleeve that prevents the notebook computer water inlet is also arranged, because wrapping up, its notebook forms an enclosed environment, not only hinder the mobile of notebook surrounding air and be unfavorable for heat radiation, and be unfavorable for the connection of computer external unit.

Now also have and can prevent that keyboard gets into the inner technology of computer to sealing from the notebook top, but water is if get into from notebook drain pan louvre, this technology is just powerless.

Summary of the invention

The purpose of this invention is to provide a kind of notebook computer drain pan louvre water inlet warning pad pasting, when notebook computer drain pan louvre is intake, can in time report to the police.

The objective of the invention is to realize like this; It comprises substrate, micro cell, control chip, hummer, A face conductive coating, B face conductive coating, glue, glue diaphragm; It is characterized in that A face conductive coating and B face conductive coating are connected on the substrate two sides, scribble glue on the A face conductive coating, be connected with the glue diaphragm on the glue; Constitute the warning pad pasting, A face conductive coating goes between respectively with B face conductive coating and is connected control chip, control chip connection micro cell and hummer.During use, stick this pad pasting, cross out the part of blocking louvre with pocket knife then and be beneficial to notebook air inlet heat radiation in the louvre zone of notebook computer drain pan.When conducting liquid flows under the notebook drain pan louvre, and touch the pad pasting that is attached on the drain pan and make sensor conducts, will trigger alarm chip, buzzer warning.After the moisture on the pad pasting is dried, the sensor stop conducting, alarm chip control hummer stops to report to the police.

The invention has the beneficial effects as follows; Present this pad pasting of Pasting all on the general visible notebook computer drain pan on the market; It is convenient to paste; Stick the heat radiation that can not influence notebook computer behind this pad pasting and be connected other functions such as peripheral hardware, just can the warning reminding user when conducting liquid touches the pad pasting on the drain pan, when the user will change or not want to continue to use pad pasting, only need tear gently gets final product.This pad pasting production technology is simple, with low cost, is easy to promote.

Substrate 2, micro cell 3, control chip, 4, hummer 5, B face conductive coating 6, A face conductive coating 7, glue 8, glue diaphragm in the drawings 1.

Embodiment

As shown in Figure 1; The present invention includes substrate 1, micro cell 2, control chip 3, hummer 4, A face conductive coating 6, B face conductive coating 5, glue 7, glue diaphragm 8; It is characterized in that A face conductive coating 6 and B face conductive coating 5 are connected on substrate 1 two sides, scribble glue 7 on the A face conductive coating, be connected with glue diaphragm 8 on the glue; Constitute the warning pad pasting, A face conductive coating goes between respectively with B face conductive coating and is connected control chip 3, control chip 3 connection micro cell 2 and hummers 4.Throw off glue diaphragm 8; Utilize glue 7 that pad pasting is sticked on the notebook computer drain pan along the A face; A face conductive coating 6 goes between respectively with B face conductive coating 5 and is connected to the trigger end of control chip 3; When conducting liquid when the B face contacts A face conductive coating 6 simultaneously and makes its conduction UNICOM with B face conductive coating 5, just can trigger alarm chip and report to the police.Sensor is on substrate, to open the hole that diameter is less than or equal to 0.3mm, is coated with conductive material on the substrate two sides and processes, at the B face; Adopt certain technology that near the conductive material the substrate hole is eaten away; At the A face, let conductive material be penetrated into the B face through aperture but and get along well 5 the contact, thereby guarantee that 5,6 neither can contact conducting; At will cut out and pad pasting can be fit to the louvre of different shape, the circuit of sensor still can not be cut off.2. batteries among the figure, 3. alarm chip, 4. hummer and connect lead and all adopt very thin original paper so that be encapsulated in and make pad pasting on the substrate, and all use insulator-coated to insulate.

Claims

1. notebook computer drain pan louvre water inlet warning pad pasting; It comprises substrate, micro cell, control chip, hummer, A face conductive coating, B face conductive coating, glue, glue diaphragm; It is characterized in that A face conductive coating and B face conductive coating are connected on the substrate two sides; Scribble glue on the A face conductive coating; Be connected with the glue diaphragm on the glue, constitute the warning pad pasting, A face conductive coating goes between respectively with B face conductive coating and is connected control chip, control chip connection micro cell and hummer.
